Technical Field

[0001] The utility model relates to the technical field of filter elements, in particular to a filter element with adjustable inlet and outlet directions. Background Art

[0002] A filter element is a device mainly used for filtering substances such as liquids or air. Through the filtration of the filter element, harmful substances such as impurities, odors, and bacteria in substances such as liquids or air can be removed, thereby improving the quality of liquids or air.

[0003] A Chinese patent with the publication number CN219885883U discloses a filter element. The key points of its technical solution are: a first sterilization layer; the first sterilization layer is sleeved outside the filter layer, and a second sterilization layer is arranged inside the filter layer. After the liquid passes through the first sterilization layer and is filtered by the filter layer, it enters the inside of the filter layer and contacts the second sterilization layer; different-density sterilization layers are arranged inside and outside the filter layer of this device, which can play a sterilization role while filtering impurities in water, adsorb through the filter layer, and water enters from the outside of the filter element, passes through the first sterilization layer, the filter layer, and the second sterilization layer, and then flows out through the through hole of the end cap. The first sterilization layer, the filter layer, and the second sterilization layer can be replaced separately according to the usage situation, reducing costs.

[0004] The existing related technologies often have the following defects: The filter elements in the existing technologies usually filter liquids or air through their surfaces. When the filtered liquids or air enter the inside of the filter element, and then the liquids or air that have been filtered inside the filter element are utilized. However, since the front and back directions of the filter element are prone to confusion, when the filter element is installed in the reverse direction, it often leads to the filter element being unable to work properly.

[0005] Therefore, the utility model provides a filter element with adjustable inlet and outlet directions. Summary of the Utility Model

A sealing cover is installed on the side of the fixing ring away from the filter element body, and a rubber pad is adhesively bonded to the side of the sealing cover close to the filter element body.

[0008] The effect achieved by the above components is: by arranging fixing rings, sealing covers and rubber pads on the upper end cover and the lower end cover, the water inlet can be flexibly determined according to the position of removing the sealing covers when the filter element needs to be installed, thereby avoiding the situation where the filter element is installed upside down as much as possible.

Detailed Implementation Manner

[0029] Referring to Figure 1 as shown, the present utility model provides a technical solution: an adjustable inlet and outlet direction filter element, including a filter element body 1, one end of the filter element body 1 is fixedly connected with an upper end cover 2, the other end of the filter element body 1 is fixedly connected with a lower end cover 3, fixing rings 4 are fixedly connected to the sides of the upper end cover 2 and the lower end cover 3 away from the filter element body 1, a sealing cover 6 is installed on the side of the fixing ring 4 away from the filter element body 1, and a rubber pad 7 is adhesively connected to the side of the sealing cover 6 close to the filter element body 1. By providing the fixing rings 4, the sealing cover 6 and the rubber pad 7 on the upper end cover 2 and the lower end cover 3, when installing the filter element, the water inlet can be flexibly determined according to the position where the sealing cover 6 is disassembled, and the situation of the filter element being installed upside down can be avoided as much as possible.

[0030] The following specifically describes its overall specific settings and functions.

[0031] Referring to Figures 1-5As shown in the figure, in this embodiment: Four positioning rods 5 are fixedly connected to one side of the fixed ring 4 close to the cover 6. By providing the positioning rods 5, it is convenient to position the cover 6 when connecting the fixed ring 4 and the cover 6, and at the same time, after moving the cover 6 close to the fixed ring 4, temporary position limitation of the cover 6 can be carried out. Two first fixing plates 8 are fixedly connected to the side surface of the fixed ring 4, and two second fixing plates 9 are fixedly connected to the side surface of the cover 6. By providing the first fixing plates 8 and the second fixing plates 9, the fixed ring 4 and the cover 6 can be connected, thereby completing the installation of the cover 6. Control rods 10 are slidably connected to the inner walls of the two second fixing plates 9, and a pull plate 13 is fixedly connected to one end of the control rod 10. The control rod 10 slidably connected to the inner wall of the second fixing plate 9 can move. By providing the pull plate 13, it is convenient to control the movement of the control rod 10.

[0032] A spring 14 is sleeved on the surface of the control rod 10, and both ends of the spring 14 are fixedly connected to the pull plate 13 and the second fixing plate 9 respectively. By providing the pull plate 13, it is convenient to install the spring 14. By providing the spring 14, the position of the control rod 10 can be restricted. A connecting plate 12 is fixedly connected to the end of the control rod 10 away from the pull plate 13. By providing the control rod 10, it is convenient to control the position of the connecting plate 12. A limiting rod 11 is fixedly connected to one side of the connecting plate 12 close to the control rod 10, and the limiting rod 11 is slidably connected to the inner wall of the first fixing plate 8.

[0033] Working principle: When a filter element needs to be installed, first select the upper end cover 2 or the lower end cover 3, pull the pull plate 13 to drive the control rod 10 to slide on the inner wall of the second fixing plate 9, so that the pull plate 13 moves closer to the second fixing plate 9. At this time, the control rod 10 drives the limiting rod 11 to move away from the first fixing plate 8 through the connecting plate 12, releasing the position limitation of the cover 6. Then move the cover 6 away from the fixed ring 4, release the pull plate 13. Under the action of the elastic force of the spring 14, the pull plate 13 moves away from the second fixing plate 9, thereby opening one end of the filter element body 1 as the water outlet, and then the filter element body 1 can be installed. By providing the positioning rods 5, it is convenient to position when installing the cover 6. By providing the rubber gasket 7, the sealing performance can be ensured as much as possible.
